White Screen On M3

On half of the games i have on my m3, they load to a white screen. i have no idea what's wrong with them. they games are :mario hoops 3 on 3, Final Fantasy III, Metroid Prime Hunters, Mario vs. Donkey Kong March of the Minis, and Castlevania Dawn of Sorrow. I have the latest fimrware.

By re-downloading them from elsewhere, or as you have a an M3 Perfect you can dump them yourself using dumper.nds (google it) because obviously you have to own the originals or what your doing is illegal.

If the card is slow several things can happen, if the game streams data from the card it will run slowly, if it loads before running it loads slowly, if it streams music and/or video it will stutter, or in extreme cases it will just white screen when trying to start the game -i would say try the catlevania test - but obviously you can't ¬_¬

I have pretty much ran out of ideas of what is wrong, sorry but I can't think of anything else that could be stopping the games from working.
